effluent volume

Two stage biological contact oxidation has many merits such as high treatment efficiency, high volume loading rate, well quality of effluent, smaller area, etc.

接触氧化法具有处理效率高，耐冲击负荷，出水水质好，占地面积小等特点。

In order to give full play to the effective volume of the sediment pool with circumferential water feed and improve the quality of effluent, uniform water distribution along the water distributing trough is a key issue.

为充分发挥周边进水沉淀池的有效容积，提高出水质量，沿配水槽均匀配水是问题的关键；

To study the permeability of topsoil, and adsorption and interception of characteristic effluent oil around proposed refinery, water seeping test has been conducted with measurement of seepage water volume once 30 minutes, and 3 hours of whole test period.

为了研究拟建炼油厂表层土壤渗透情况及对特征污染物油的吸附和截留情况，实施了渗水实验，每隔30min测定一次渗水量，渗水实验时间为3h。

To reach the new effluent discharge standard, COD volume loading rate should be lower than 0.67 kg/ ( m 3 · d).

要使COD达到新的排放标准，进水COD容积负荷应低于0.67kg/（m3·d）（该负荷下出水COD在100mg/L上下波动，平均为106.3mg/L）；
